Gibbocicada brasiliana, new genus and new species from Brazil and a key for the genera of Tibicinini (Hemiptera: Auchenorrhyncha: Cicadidae)

Abstract

Abstract Four examined specimens from Brazil, Ceará, with morphological characteristics belonging to Tibicinini (Hemiptera: Cicadidae) revealed an undescribed genus and species. Gibbocicada brasiliana gen. et sp. nov., representing the first record of Tibicinini in Brazil, is recognized mainly for the head three times shorter than pronotoum in dorsal view, the lateral ocelli almost reaching the anterior margin of pronotum, the pronotum and mesonotum pronounced dorsally in lateral view, and the fore wings with the median and cubitus anterior veins rising from the same point in the basal cell. A key to the genera of Tibicinini is presented.
